About
Fullstack and autonomous Software Engineer, I have built tools and client-facing applications for multiple companies, all while setting up the guidelines, and owning both the projects I created and the infrastructure it runs on.
With several years of experience across France and Bulgaria, I can contribute quickly after joining a team or project. Generally curious, I always look for the best solution to any given problem.
